Assembly: mscorlib (in mscorlib.dll)
The following code example shows how to reliably set handles using the PrepareConstrainedRegions method. To reliably set a handle to a specified pre-existing handle, you need to ensure that the allocation of the native handle and the subsequent recording of that handle within a SafeHandle object is atomic. Any failure between these operations (such as a thread abort or out of memory exception) will result in the native handle being leaked. You can use the PrepareConstrainedRegions method to make sure that the handle is not leaked.
